I just installed cpp-ethereum 1.2.2 in order to upgrade to Homestead. When eth is started it begins to re-sync the blockchain from block 1, while the whole blockchain is already on my machine.
Is this necessary?
Is there a way to reuse the blockchain already present in .ethereum/chaindata?

The Go Ethereum (geth) and Turbo Ethereum (eth) do not share the same blockchain and data directory. If you switch your client from geth to eth you will have to redownload the whole blockchain again. Also you have to migrate your accounts.
